Logan, Alan C, Martin A Katzman, and Vicent Balanzá-Martínez. “Natural Environments, Ancestral Diets, and Microbial Ecology: Is There a Modern ‘paleo-Deficit Disorder’? Part II.” Journal of Physiological Anthropology 34.1 (2015): 9. PMC. Web. 30 Apr. 2017.
"Famed microbiologist René J. Dubos (1901–1982) was an early pioneer in
the developmental origins of health and disease (DOHaD) construct. In
the 1960s, he conducted groundbreaking research concerning the ways in
which early-life experience with nutrition, microbiota, stress, and
other environmental variables could influence later-life health
outcomes. He recognized the co-evolutionary relationship between
microbiota and the human host. Almost 2 decades before the hygiene
hypothesis, he suggested that children in developed nations were
becoming too sanitized (vs. our ancestral past) and that scientists
should determine whether the childhood environment should be “dirtied up
in a controlled manner.” He also argued that oft-celebrated growth
chart increases via changes in the global food supply and dietary
patterns should not be equated to quality of life and mental health.
Here in the second part of our review, we reflect the words of Dubos off
contemporary research findings in the areas of diet, the gut-brain-axis
(microbiota and anxiety and depression) and microbial ecology. Finally,
we argue, as Dubos did 40 years ago, that researchers should more
closely examine the relevancy of silo-sequestered, reductionist findings
in the larger picture of human quality of life. In the context of
global climate change and the epidemiological transition, an allergy
epidemic and psychosocial stress, our review suggests that discussions
of natural environments, urbanization, biodiversity, microbiota,
nutrition, and mental health, are often one in the same."
Elements of paleo-deficit disorder listed include:
↓Natural light, particularly daytime blue light
↓Physical activity in natural habitats
↓Visual contact with sights, smells and sounds of biodiverse habitats
↓Consumption of natural foods
↓Contact with non-pathogenic microbial diversity
↓Opportunity for privacy and solitude
↓Direct contact with Earth (aka grounding) in daily life; living and sleeping in artificial footwear and electromagnetic environments that insulate us from the negatively charged electron supply of the Earth
↓Exposure to negatively charged air ions
There exists evidence that all of these aspects of civilized life have a negative impact on our health.
Humans are in fact by Nature wild animals and it seems likely that the proliferation of diseases we experience in civilized (i.e. domesticated) circumstances are not due to only one factor (e.g. diet) but to all of the above factors plus perhaps others we've not yet identified AND dysgenic influences exerted by modern medicine and culture.
